본 발명은 도로와 공항(이하 "도로"라 함)의 노면 포장상태를 조사하는 장치에 관한 것으로, 특히 도로의 포장 상태를 종합적으로 자동 조사하여 그 결과를 객관적인 자료로 저장 제공할 수 있게 한 도로의 노면 포장 상태 자동 조사 장치에 관한 것이다.The present invention relates to a device for inspecting road pavement conditions of roads and airports (hereinafter referred to as "roads"), and in particular, a road that enables comprehensive automatic investigation of road pavement status and stores and provides the result as objective data. The road pavement state of the present invention relates to an automatic irradiation device.

많은 차량이 주행하는 도로의 노면은 차량의 주행 저항과 차량의 무게 등으로 인하여 항상 무거운 하중 또는 충격이 가해지고 있는 상태이기 때문에, 도로의 노면에 많은 변형이 생기게 된다.Since the road surface on which many vehicles travel is always under heavy load or impact due to the running resistance of the vehicle and the weight of the vehicle, many deformations are generated on the road surface of the road.

도로의 노면 파손은 차량의 주행 상태를 나쁘게 하여 여러 가지 불편한 문제를 야기하는데, 이러한 문제는 포장이 되지 않은 도로 뿐만 아니라 아스팔트나 콘크리트가 포장된 도로에서도 발생되게 된다.Road breakage of the road worsens the driving condition of the vehicle and causes various inconveniences. This problem occurs not only on unpaved roads but also on asphalt or concrete paved roads.

한편, 일반 시가지의 노면 상태를 항상 깨끗하고 정상적인 상태로 유지관리 하기 위해 구청이나 시청의 도로 보수과 등에서 항상 시가지 도로를 점검하고 있는데, 그 점검 결과를 토대로 하여 유지 보수 계획을 세우게 된다.On the other hand, in order to maintain the road surface condition of the general city always clean and normal state, the road repair department of the ward office or the city hall is always checking the city roads, and the maintenance plan is established based on the inspection result.

그런데, 일반적인 기존의 도로 및 공항 노면 포장 상태를 점검하는 방법은 도로 보수과의 직원이 직접 도로에 나가서 도로의 상태를 점검하고 그 점검 결과를 보고하면, 그 보고 사항에 따라 도로의 유지 보수 상태를 결정하게 된다.By the way, the general road and airport road pavement condition check method, if the staff of the road maintenance department goes directly to the road to check the state of the road and report the inspection result, the road maintenance status is determined according to the report Done.

그런데, 이러한 경우에 도로의 노면 상태를 파악한 직원의 개인적인 보고 결과만을 토대로 하여 도로의 유지 보수를 결정하여야 하기 때문에, 보수의 우선 순위 등을 결정하는데 객관성이 떨어지게 되고, 현장에 출동하지 않은 상급자가 정확한 판단을 할 수가 없는 객관성 등의 문제가 있었다.However, in this case, since the maintenance of the road should be decided only on the basis of the personal report of the employee who grasped the road condition of the road, the objectivity in determining the priority of the repair falls, and the senior who did not go to the site There were problems such as objectivity that could not be judged.

이에 본 발명은 상기한 바와 같은 종래의 일반적인 도로의 노면 포장 상태를 조사하는 방법에 따른 문제를 해결하여, 도로의 노면 포장상태를 자동적이면서 종합적으로 조사하여 그 결과를 영상 및 수치화하여 저장할 수 있게 하여 도로의 포장 상태를 과학적이고도 객관적으로 정확하게 파악할 수 있게 한 도로의 포장 상태 자동 조사 장치를 제공하는데 그 목적이 있다.Accordingly, the present invention solves the problem according to the method of investigating the road pavement state of the conventional general road as described above, by automatically and comprehensively inspecting the road pavement state of the road so that the result can be imaged and digitized and stored An object of the present invention is to provide an automatic road pavement inspection apparatus that can accurately and accurately understand the pavement status of the road.

상기한 바의 목적을 달성하기 위한 본 발명의 장치는, 차량에 포장도로 표면의 파손 상태를 촬영하는 노면촬영 기구와, 도로의 노면 굴곡 상태를 측정하는 노면 러팅 측정기구, 도로의 종단 평탄성을 측정하는 평탄성 측정기구, 위치파악 및 기록을 위한 기록 기구, 자료 분석 저장 기구, 도로의 전후좌우 전경을 촬영하는 촬영기구, 도로의 주행 소음을 측정하는 주행 소음 측정 기구 및 전력을 공급하는 기타 보조기구를 구비하여 이루어진다. The apparatus of the present invention for achieving the above object is a road surface photographing mechanism for photographing the damaged state of the pavement surface on the vehicle, a road surface rutting measuring mechanism for measuring the road curvature of the road, the end flatness of the road Flatness measuring device, location and recording device, data analysis storage device, photographing device for photographing the front, rear, left and right views of the road, driving noise measurement device for measuring the running noise of the road, and other auxiliary devices for supplying power. It is made.

이러한 구조로 이루어진 본 발명의 장치는 검사를 하기 위한 도로를 따라 주행하면서 도로의 노면 포장 상태나 주변 상황 등을 종합적으로 조사하여 누구나 알기 쉬운 객관적인 자료를 만들어 제공할 수 있게 하여, 도로의 유지 보수 및 사후 사전관리를 위한 종합적인 자료를 과학적, 객관적으로 제공할 수 있게 한다.The device of the present invention having such a structure allows the user to make and provide objective data that is easy for anyone to understand by comprehensively inspecting the road pavement and surrounding conditions of the road while driving along the road for inspection.
